The recipe your aunt never wrote down is a family library with one copy. Stand in the kitchen and watch.

Skills that live in a person’s hands were never written down, because the one doing them does not experience them as information. Ask for the recipe and you get approximate quantities and the word until, because the real instructions are judgement: what the dough should feel like, when to stop. That knowledge goes with the person unless somebody stands next to them.

Go and watch rather than asking for a list. Take notes on what they do, not what they say they do. Then cook it yourself while they are still there to correct you.
